STOVEHPIPE JOINT AND THINIBLE=LOCK.

SPECIFICATION forming part of Letters Patent No. 356.706, dated January 25, 1887.

Application iiled July El, 1836. Serial No. $208,600, (No model.)

.To @ZZ whom, 1175 may concern.-

Be it known that I, Enna G. GAMERON, a citizen of the United States, residing at Charlotte, in the county of Eaton and State of Michigan, have invented certain new and useful Improvements in Stove-Pipe Joints and Thimble-Locks, of Vwhich the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to steve-pipe couplings and locks, its obje-ct being to secure the stove pipe within the crack or opening through the wall of the building in which they are to be used, as also to connect the several joints together in a secure and economical manner, as will he hereinafter fully set forth.

In the accompanying drawings,maling part ofthis speeicntion,Figi1reIrepresentsalongitndinal section of the connecting-pipes with section oi' masonry. Fig. 2 is a perspective of a device to which the first section of pipe is to be connected. Figs. 3, 4, 5, and 6 are detached views of several parts, showing the mode of connecting the parts and their construction.

In the rigores, A represents the masonry or bricloworl; surrounding the openingin which the pipe is to he inserted.

B represents a thimble, ilanged at each end, which is built in with the masonry and permanently held there.

E is a sheet-metal plate, concave on its upper surface, the outer portion of which plate is longitudinally slitted and then bent thrice to form the curved external flange II and clampingflaiige c, and its under portion similarly slitted and bent thrice to forni the curved external flange, I, and the continuation of the curved main body E, in the same cylindrical plane therewith.

The flanges formed bythe bends in the plate E are marked II and I. These liauges are sufficiently far apart to t snugly over the two ends of the thimbie B, as seen in Fig. l. In the ring E is a diamondvshaped or oval open- O represents a sectionof pipe, the inner end of which, after passing into the thimblc and over the plate E, catches under the flange e of the plate. This section is also provided with an opening to correspond with the shape of that in ring E.

D represent-s another section of pipe, which enters the enter end of section C. It is also provided with n. similar hole or opening to those above referred to.

d represents a. keybolt for the purpose or" securing the parts together. This bolt has an annular flange, a', a shank, n., and an arrow flanged head, mi. The end of this bolt may be arrow, diamond, or oval shaped to correspond with the opening o, through which it has to enter in securing the parts together. A quartertnrn of the bolt will bring its flanges in the position represented fully in Fig. 1;whereby all of the parts are clamped securely together. The ilange a: extends over the openings in the sections, so as to prevent escape of smoke or soot.

As many sections of pipe may be connected together as desirable by means of bolts shaped as the one represented and through similarly,7n shaped holes.

On greet advantage in the pointed arrowsheped bolt is it readily enters the openings in the sections and draws them together or moves them to proper position. This is very desirable on account oi" the quickness and ae curacy with which the sections can be joined.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combina-tion, with the thirnble B, of the stove-pipe sectiomond the concave section E, formed with flanges H I, and aretaining-fastening securing it to the stove-pipe seetion, substantially as described.

2. The retaining-plate E, concave on its npper surface, provided with flanges H I, formed by slitting and bending the metahas described, and provided with an aperture adapted to receive a suitable fastening, as specified.

In testimony `whereof I affix my signature in presence of two Witnesses.

EZRA G. CAMERON.
